I recently noticed the back right door playing up a few weeks back. It would unlock only after the other doors unlocked. But it would open/shut fine and with family/work etc I didn't have time to address it.
Now it won't open with either indoor/outdoor/both handles.
VCDS says implausible signal and door lock module faulty. I want to work out where the problem lies and I suspect t's the lock module but how can I take off the door skin if the door is stuck shut?
